Answers
Explanation:
A, C and F are function
B is not a function because one of the domain which is 2 has two range mapped.
As for D and E I’m not entirely sure about that.
If an arrow diagram represented a function, every value in the input would go to its own unique output. In other words, one number on the left side can only go to one certain number on the right side. Now that we know this, let’s answer the questions. I will answer yes if it is a function and no if it isn’t, as well as the explanation.
a) Yes
b) No. 2 goes to both a and b.
c) Yes
d) Yes
e) Yes
f) Yes

a square + 7 a + 12 =A + 4
Answers
Step-by-step explanation:
[tex] {a}^{2} + 7a + 12 = a + 4 \\ {a}^{2} + 7a - a - 4 + 12 = 0 \\ {a}^{2} + 6a + 8 = 0 \\ {a}^{2} + 4a + 2a + 8 = 0 \\ a(a + 4) + 2(a + 4) = 0 \\ (a + 4)(a + 2) = 0 \\ a + 4 = 0 \: or \: a + 2 = 0 \\ a = - 4 \: or \: a = - 2[/tex]
Answer:
a = -4 or a = -2
Step-by-step explanation:
a² + 7a + 12 = a + 4
=> a² + 7a - a + 12 - 4 = 0
=> a² + 6a + 8 = 0
=> a² + 2a + 4a + 8 = 0
=> a(a + 2) + 4(a + 2) = 0
=> (a + 4)(a + 2) = 0
=> a = -4 or a = -2

Find (f - g) (x)
f(x) = 2x^2 – 2 and g(x) = 4x + 1
6x2
Answers
Answer:
(f - g) (x) = 2x^2 - 4x - 3
Step-by-step explanation:
(f - g) (x) = f(x) - g(x)
(f - g) (x) = 2x^2 - 2 - (4x + 1)
(f - g) (x) = 2x^2 - 2 - 4x - 1
(f - g) (x) = 2x^2 - 4x - 3
A bag of sweets contains mints and toffees only.There are 21 mints in the bag.One quarter of the sweets are toffees.Calculate the total number of sweets in the bag.
Answers
Answer:
Total number of sweets in the bag is 28
Step-by-step explanation:
let the total number of sweets in the bag be x :
[tex]{ \tt{for \: toffees : }} \\ \frac{1}{4} \: of \: x[/tex]
therefore fraction of mints = 1 - fraction of toffees :
[tex] = \frac{4}{4} - \frac{1}{4} \\ \\ = \frac{3}{4} [/tex]
therefore:
[tex] = > \frac{3}{4} \: of \: x = 21 \: mints \\ \\ \frac{3}{4} \times x = 21 \\ 3x = 21 \times 4 \\ x = \frac{21 \times 4}{3} \\ x = 28[/tex]
total sweets number is 28

Answer:
7⅔ pounds to be shared 1⅓ per container.
For a clearer and swift understanding
Change them from Mixed NUMBERS to simple fractions
7⅔ = 23/3
1⅓ = 4/3
Now
We need to Fill 23/3 pounds of walnuts by 4/3 each into a container
Simply divide 23/3 by 4/3 to know how many walnuts that would enter
23/3 ÷ 4/3
23/3 x 3/4 = 23/4.
SO 23/4 CONTAINERS WOULD BE FILLED.
23/4 containers when converted to mixed numbers is
5¾.
This is our answer.
But Looking at the Question
5¾ has been broken to two fractions.
The Number that'll fill the blank space is 5.
Why? 5 + 9/12 = 23/4 which is the answer we got initially.
ANSWER = 5
Hope it helps tho.

x=19y=38Step-by-step explanation:
Let x be the smaller number
Let y be the larger number
The larger of 2 numbers is twice the smaller number :
[tex]y = 2x[/tex]
if 12 is subtracted from the larger number the result is 7 more than the smaller number :
[tex]y-12 = 7+x[/tex]
To solve for x ;
Substitute 2x for y in the second equation
[tex]2x-12=7+x\\2x-x=7+12\\x = 19[/tex]
To solve for y
[tex]If\: y=2x ,\\y = 2\times 19\\\\y= 38[/tex]

2.8 2.08 and 2.008 in order
Answers
Answer:
2.008, 2.08, 2.8
Step-by-step explanation:
You basically have to go in order of the tens, hundreths, and thousandths place. So first is the thousandths place which is the third digit after the decimal. That would be 2.008, then the one that has a hundredths place is 2.08, and then the tenths place with the 2.8
Thousandths are least than the hundredths and the hundredths are least than the tenths. Just remember that!
